System that technical scheme that the embodiment of the present invention is provided uses as shown in figure 1, main by terminal server group
Become, the method and system that the embodiment of the present invention is provided is realized in server side, be mainly used in obtaining terminal in sampling from terminal
The positional information of point, then obtains target concern position according to terminal in the positional information of sampled point.The embodiment of the present invention is to end
The function at end is not changed, and will be sent to server by the positional information of itself.Wherein, described terminal can include navigating
Terminal and user equipment, described user equipment can include personal computer (personal computer, pc), notebook electricity
Brain, mobile phone or panel computer.
The embodiment of the present invention provides a kind of acquisition methods of transport information, refer to Fig. 2, it is carried by the embodiment of the present invention
For transport information acquisition methods schematic flow sheet, as illustrated, the method comprises the following steps:
S201, obtains the positional information in n sampled point for the terminal, n is the integer more than or equal to 3.
Specifically, the server receiving terminal cycle send terminal n sampled point positional information, n be more than or
Integer equal to 3.
Preferably, terminal can include position collection module, and this position collection module can call the behaviour of terminal periodically
The interface of system offer is provided, to obtain the positional information of terminal, then sends the terminal obtaining in the position of sampled point to server
Confidence ceases；For example, position collection module can just obtain the positional information of a terminal at interval of 10s；Wherein, sampled point refers to
It is the moment of the positional information that position collection module obtains terminal, thus the end that the position collection module of terminal sends to server
The positional information in sampled point is held to substantially comprise positional information and the corresponding sampled point of this positional information of terminal.
Illustrate, position collection module can call the interface that the operating system of terminal provides periodically, to obtain end
The method of the positional information at end can include following two:
The first: position collection module can call the global positioning system that the operating system of terminal provides periodically
(global positioning system, gps) interface, is detected with obtaining in gps module a period of time recently from gps module
The positional information of the terminal arriving.
Second: when terminal does not open gps function or cannot use gps work(due to reasons such as weather, hardware damage
During energy, position collection module can call the Wireless Fidelity (wireless- that the operating system of terminal provides periodically
Fidelity, wi-fi) interface, obtain at least one wi-fi focus of terminal surrounding from wi-fi module, this wi-fi focus can
To include wi-fi focus and/or the unencrypted wi-fi focus of encryption.Then, position collection module is according at least one wi-
Fi focus, from default wi-fi data base, obtains each corresponding positional information of wi-fi focus, then according to each wi-fi
The corresponding positional information of focus, obtains the positional information of terminal.
For example, the wi-fi focus of terminal surrounding that position collection module obtains includes: wi-fi1, wi-fi2 ..., wi-
fi n；Corresponding, the positional information obtaining from wi-fi data base includes: (x1,y1)、(x2,y2)、……、(xn,yn), position is received
The positional information of the terminal that collection module obtains according to these positional informationes is ((x1+x2+……+xn)/n,(y1+y2+……+yn)/
n).
Preferably, this position collection module can also obtain terminal in sampled point in the location client end from terminal periodically
Positional information；For example, described location client end can include the energy such as microblogging client, wechat client, Renren Network client
Enough realize the client of positioning function.
S202, in the positional information according to described n sampled point, the positional information of m-th sampled point, the m-1 sampling
Point positional information and m+1 sampled point positional information, acquisition described terminal translational speed change, m be more than or
Person is equal to 2, and the integer less than or equal to n-1.
Specifically, first, server can be adopted for m-th according in the positional information of the n sampled point receiving from terminal
The positional information of sampling point and the positional information of m-1 sampled point, obtain the first translational speed；And according to the m+1 sampling
The positional information of point and the positional information of m-th sampled point, obtain the second translational speed.
For example, server can be with the positional information (x of m-th sampled pointm,ym) with the positional information of m-1 sampled point
(xm-1,ym-1) difference, divided by the sampling interval between m-th sampled point and the m-1 sampled point, obtain the first mobile speed
Degree, the average shifting of terminal in the sampling interval that this first translational speed refers between m-th sampled point and the m-1 sampled point
Dynamic speed；In the same manner, server can be with the positional information (x of m+1 sampled pointm+1,ym+1) with the position of m-th sampled point letter
Breath (xm,ym) difference, divided by the sampling interval between m+1 sampled point and m-th sampled point, obtain the second translational speed,
This second translational speed refers to the average movement of terminal in the sampling interval between m+1 sampled point and m-th sampled point
Speed.
Optionally, server can count terminal in a period of time according to the first translational speed and the second translational speed
Then average translational speed is more than the terminal of default threshold speed as target terminal by average translational speed.For example, service
Device can be the average translational speed of terminal of every 5 minutes statistics；Again for example, default threshold speed can be 40 kilometers/
Hour, the terminal that translational speed average in 5 minutes can be more than 40 kilometers/hour is as target terminal.
It should be noted that so that target concern position is the position of electronic eye as a example, average translational speed is more than default
The terminal of threshold speed is only possible to be to drive the terminal of user, just has reference value, and average translational speed is less than or waits
In default threshold speed terminal although it is possible to being to drive the terminal of user, but be because the average translational speed of terminal relatively
Little, typically will not exceed the speed limit, so the translational speed data of the average less terminal of translational speed does not have reference value, so needing
Using default threshold speed, terminal is screened, to determine target terminal.In addition, what the user that drives can include driving
User and user by bus, although user by bus is simply by bus, the translational speed of the terminal of user by bus can also
Embody the transport condition of vehicle, therefore there is reference value.
Then, server can obtain described movement according to the difference of described second translational speed and the first translational speed
The change of speed.Preferably, the change of the translational speed of target terminal if server obtains target terminal, can only be obtained；
If server does not obtain target terminal, the change of the translational speed of all terminals can be obtained.
S203, according to the change of the translational speed of described terminal, obtains target concern position.
Specifically, when driving, user can judge that translational speed at that time is after range estimation is to electronic eye taking electronic eye as a example
No hypervelocity, if translational speed hypervelocity at that time, can actively brake to reduce translational speed, it is therefore contemplated that translational speed
Reduce, but the corresponding position of sampled point that translational speed is not reduced to 0 is candidate's concern position.Based on this principle, first, clothes
Business device can obtain first candidate's concern position according to the change of the translational speed of described terminal.
Illustrate, taking electronic eye as a example, change to the translational speed according to described terminal for the server, obtain the first time
The method of choosing concern position illustrates: if the change of the translational speed of described terminal is less than 0, and the second translational speed is not equal to
0, represent that the second translational speed is less than the first translational speed, illustrate that the translational speed of m-th sample point terminal starts to reduce, then
M-th sampled point can pay close attention to position as the first candidate, and that is, m-th sampled point can be used as the electronic eye position of candidate；If
The change of the translational speed of described terminal is equal to 0, represents that the second translational speed is equal to the first translational speed, and m-th sampling is described
At point, the translational speed of terminal does not reduce and does not improve yet, and m-th sampled point is not first candidate's concern position, that is, m-th
Sampled point is not the electronic eye position of candidate.If the change of the translational speed of described terminal is more than 0, represent that the second translational speed is big
In the first translational speed, illustrate that the translational speed of m-th sample point terminal is improved, m-th sampled point is not the first candidate
Concern position, that is, m-th sampled point cannot be used as the electronic eye position of candidate.
Then, after obtaining first candidate's concern position, server can be right according to default distance threshold for server
Adjacent described first candidate's concern position merges process, to obtain second candidate's concern position.
Illustrate, server, according to default distance threshold, closes to adjacent described first candidate's concern position
And process, may include that server calculates each two first candidate concern position with the method obtaining second candidate's concern position
The distance between, then according to default distance threshold, obtain two first candidate's concern positions that distance is less than this distance threshold
Put, and this two first candidate's concern positions are merged, to obtain second candidate's concern position.For example, second candidate's concern position
It is set to the midpoint that this two the first candidates pay close attention to position.Using the method, some first candidate's concern positions can be closed
And, obtain second candidate's concern position.So iterative cycles, pay close attention to position to the second candidate and merge process, until second
The distance between candidate's concern position both greater than or is equal to stopping circulation during default distance threshold.For example, described default
Distance threshold can be equal to 30 meters.
Finally, after obtaining second candidate's concern position, server can obtain described second candidate's concern to server
The reduction of speed frequency of position, the described second candidate's concern position described reduction of speed frequency being more than default frequency threshold is as described
Target pays close attention to position.
Illustrate, server calculates the reduction of speed frequency that the second candidate pays close attention to position, this reduction of speed frequency is equal to the second candidate
At concern position, the terminal number of reduction of speed is divided by corresponding natural law；Wherein, server can obtain second candidate concern position it
The translational speed of terminal after the translational speed of front terminal and the second candidate concern position, according to the change of this two translational speeds
Obtain the number that the second candidate pays close attention to the terminal of reduction of speed at position.Reduction of speed frequency is more than the of default frequency threshold by server
Position is paid close attention to as target in two candidate's concern positions, and for example, described target pays close attention to the position of the electronic eye that position is just to determine.Example
As described frequency threshold can be equal to 100, even have the terminal of more than 100 to pay close attention to position in the second candidate daily and reduce shifting
Dynamic speed, illustrates that this second candidate concern position has universality, then position is paid close attention to for target, instead in this second candidate concern position
It, second candidate's concern position is not target concern position.
After described step s203, the acquisition methods of above-mentioned transport information can also include: according to the movement of described terminal
The change of speed, obtains the speed-limiting messages that described target pays close attention to position.
Specifically, first, after obtaining target concern position, server can obtain each terminal and close in described target
The translational speed of note position.
For example, certain customers are had not see electronic eye in driving procedure or deliberately break rules and regulations without reducing mobile speed
Degree, the presence of this certain customers is rational, and the ratio of this certain customers is less, and such as ratio is 5%, therefore can be by this portion
The translational speed dividing the terminal of user excludes, and therefore, is obtaining terminal after the translational speed of target concern position, server
Can be according to ascending order, the translational speed paying close attention to position in described target to described terminal is ranked up, to obtain
Ranking results；Server, according to default ratio value (as 95%), obtains in described ranking results and ranks forward described movement
Speed；Remove 5% of maximum in translational speed, retain 95% of minimum in translational speed.
Finally, the change of the translational speed according to described terminal for the server, described translational speed and default speed limit threshold value,
Obtain the speed-limiting messages that described target pays close attention to position.
Illustrate, server, according to the change of the translational speed of terminal, obtains, at target concern position, the row that slows down occurs
For terminal, then from above-mentioned 95% translational speed, obtain the translational speed that these terminals pay close attention to position in target, and count
Calculate the meansigma methodss that target pays close attention to the translational speed of terminal at position, according to meansigma methodss and the default speed limit threshold value of this translational speed
(as 40 kilometers/hour, 60 kilometers/hour, 80 kilometers/hour, 100 kilometers/hour, 110 kilometers/hour and 120 kilometers/little
When), obtain the speed restrictive block that the meansigma methodss of translational speed are located, the higher limit of this speed restrictive block is paid close attention to position as this target
Speed-limiting messages.For example, at certain target concern position, the meansigma methodss of the translational speed of terminal are 70 kilometers/hour, this 70 kilometers/
The speed restrictive block that hour is located is 60 kilometers/hour～80 kilometers/hour then it is assumed that the speed-limiting messages that this target pays close attention to position are
80 kilometers/hour.
It should be noted that only paid close attention to by target in the embodiment of the present invention illustrating as a example the position that position is electronic eye
, but target pays close attention to the position that position is not limited to electronic eye, can also include road construction position, the multiple position of vehicle accident
Put etc. and to need user to need the position paid close attention in driving procedure.
